Different methods for allocating the joint costs of water supply projects among users are compared on basis certain commonsense principles equity. We contrast separable costs‐remaining benefits (SCRB) method with simple proportional allocation schemes and more sophisticated from cooperative game theory, including Shapley value variants core. Advantages disadvantages in practice examined using a regional system Sweden. It is argued that these provide useful framework choosing intelligently...

Abstract Numerous COVID-19 diagnostic imaging Artificial Intelligence (AI) studies exist. However, none of their models were potential clinical use, primarily owing to methodological defects and the lack implementation considerations for inference. In this study, all development processes deep-learning are performed based on strict criteria “KAIZEN checklist”, which is proposed previous AI guidelines overcome deficiencies mentioned above. We develop evaluate two binary-classification triage...

Total-body CT scans are useful in saving trauma patients; however, interpreting numerous images with varied window settings slows injury detection. We developed an algorithm for "unified total-body image multiple organ-specific windowings (Uni-CT)", and assessing its impact on physician accuracy speed interpretation. From November 7, 2008, to June 19, 2020, 40 cases of blunt injuries, were collected from the emergency department Osaka General Medical Center randomly divided into two groups....

We compared surgical outcomes in patients with either primary open-angle glaucoma or exfoliation after undergoing combined phacoemulsification a 120° 180° incision during Schlemm’s canal microhook ab interno trabeculotomy (μLOT-Phaco). This retrospective comparative case series examined 52 μLOT-Phaco eyes that underwent surgery between September 2017 and December 2020. Surgical qualified success was defined as an intraocular pressure (IOP) of ≤20 mmHg, ≥20% IOP reduction IOP-lowering...

This study retrospectively examined the mid-term surgical outcomes between microhook ab interno trabeculotomy (μLOT) and goniotomy when one was using Kahook Dual Blade (KDB) in combination with phacoemulsification primary open-angle glaucoma exfoliation patients. Between December 2016 2020, current 47 μLOT 52 KDB eyes that underwent surgery. When there a < 20% reduction preoperative intraocular pressure (IOP) or IOP > 18 mmHg (criterion A), 14 B) at two consecutive follow-up visits,...

BackgroundRecent studies suggested an expected survival benefit associated with anticoagulant therapies for sepsis in patients disseminated intravascular coagulation (DIC). However, overt DIC are no longer assumed to regulate pathologic progression as is a late-phase disorder. Therefore, methods early prediction of sepsis-induced before its stage strongly required.ObjectivesWe aimed develop model using machine learning.MethodsThis retrospective, observational study included adult septic...
